:: Actually, if you [https://www.wolframalpha.com/input/?i=integrate+1%2Fsqrt%282+*+pi%29+*+exp%28-x%5E2+%2F+2%29+from++-0.001+to+0.001 integrate] a normal distribution <math>\mathcal{N}(0,1)</math> from <math>-\frac{\sigma}{1000}=-0.001</math> to <math>+\frac{\sigma}{1000}=0.001</math>, you'll get a range of about 0.08% of all values. This would be bad because it would mean that, as big as the confidence interval appears in the picture, the more meaningful 1- or 3-sigma interval (whose size represents the uncertainty of the model) would be larger by a factor of 1250 or 3750, respectively. --[[User:Koveras|Koveras]] ([[User talk:Koveras|talk]]) 08:38, 26 May 2020 (UTC) | :: Actually, if you [https://www.wolframalpha.com/input/?i=integrate+1%2Fsqrt%282+*+pi%29+*+exp%28-x%5E2+%2F+2%29+from++-0.001+to+0.001 integrate] a normal distribution <math>\mathcal{N}(0,1)</math> from <math>-\frac{\sigma}{1000}=-0.001</math> to <math>+\frac{\sigma}{1000}=0.001</math>, you'll get a range of about 0.08% of all values.

:Perhaps you heard about [https://en.wikipedia.org/wiki/Six_Sigma Six Sigma], a quality method used by General Electric (among others) to keep specifications and processes within tiny tolerances. The six sigmas mean that even absolute (so-called) outliers in your production are within the strict tolerances. With milli-sigmas it is extremely seldom to get an acceptable result at all.
